Promoters are

• genes that code for individual proteins
• proteins that bind with DNA and prevent transcription
• DNA sequences near operons that regulate transcription
• small molecules that bind with repressor proteins

The process by which the genetic code of DNA is copied into a strand of RNA is called

• translation
• transcription
• transformation
• replication

Which of the following describes RNA?

• RNA is usually double-stranded and contains the base thymine
• RNA is usually single-stranded and contains the base uracil
• RNA is longer than DNA and uses five bases to encode information
• RNA is made in the nucleus of eukaryotic cells and stays there to carry out its functions

In messenger RNA, each codon specifies a particular

• nucleotide
• enzyme
• amino acid
• promoter

The number of codons in the genetic code is

• 3

• 4

• 20

• 7

The process of making proteins on the ribosome based on instructions from messenger RNA is called

• transcription
• transformation
• translation
• molecular biology

Changes is DNA sequences that affect genetic information are known as

• replications
• mutations
• transformations
• translations
